[quote name='Ryuukishi']I play my PS2 games on an HDTV, and frankly, the results are not great. Component cables are a must, of course, and any game that supports progressive scan will look much cleaner.
Some games look a lot better than others, and sometimes you even have different results within the same game, as with Final Fantasy XII where normal gameplay looks all right, but the FMVs were a complete pixelated mess. Other random observations: With Final Fantasy X and X-2, exploration gameplay looks okay but the battles are blurry and ghosty (do battles run at a different resolution?). Cel-shaded games like Dragon Quest VIII and Rogue Galaxy tend to look blocky. Persona 3 and God of War look pretty damn good all-around. Wild ARMs 5 also looks very nice, except for the overworld exploration which has the same problems as FFX's battles. Etc., etc.
In short, mileage definitely varies depending on the graphical style of the game, but with practically every game you're going to notice at least some blocky/blurry/jaggy stuff going on. The fact is that your television has to blow up that image to a size and level of detail that the PS2 is just not equipped to handle.
One more bit of advice, unless the game actually supports 16:9 aspect ratio, don't be tempted to play it on 16:9. Just change the television's display mode to 4:3 and deal with the black columns, unless you want every game to look like an absolute blurry abortion.
(Oddly enough, I've had much better overall results with GameCube games. Twilight Princess, F-Zero GX, and Wave Race: Blue Storm in particular look fantastic on my television.)

no surprise, AAA gamecube games have much better graphics than ps2 games. GoW is an exception and would probably look good on an HDTV considering it has progressive scan.
